The window size is not stored in the compressed data stream and must be known before decoding begins.

The window size should be the smallest power of two between 2^17 and 2^25 that is greater than or equal to the sum of the size of the reference data rounded up to a multiple of 32_768 and the size of the subject data. However, some implementations also seem to support a window size of less than 2^17, and this one is no exception.

Trait Implementations

impl Clone for WindowSize

fn clone(&self) -> WindowSize

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for WindowSize

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for WindowSize

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for WindowSize

fn eq(&self, other: &WindowSize) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
